Nope. They're different sizes. Compare iFixit's guide to replacing a 15" early 2011 battery to their guide for a 2010 13": 15": 13": Both batteries are roughly proportional to their cases, and the 15" has a substantially bigger case than the 13". Additionally, they're shaped differently - see the little notch in the top left of the 15" battery, which ...

You can leave your battery unchanged as long as you want, even it is not recommended by the operating system (i.e. Apple). From my own experience (2011 MacBook Air with 1178 load cycles), the battery performance will just degrade more. It may be be months away, but at one point the battery will be so weak that an unplugged Mac will not go to sleep when ...

I had the same problem with my trusty iPod which I had plugged into my Audi's adapter. It worked perfect for years. I recently moved it to my new Audi (which no longer has a built in adapter). Up came a message "connect to power" with a picture of a battery. Plugged into USB outlet on my car with a cord I had not used in years and no luck, then plugged into ...

As Allendar's comment said, read the documentation and help. I suspect it will say something along the lines that you should connect the charger whenever power is available, and avoid a deep discharge. These days I suspect the software will protect you as well. By deep discharge I mean to keep running the computer from battery power beyond the limit ...

Since it's impossible for a battery to deteriorate that quickly for a new unit, let's check several factors to find out who're the battery eaters. The easiest way to find out battery killer is via activity monitor > energy. There you could find out the energy impact of individual apps. Perhaps you might notice some apps that weren't intended to run in the ...

I had this issue with my new MacBook Pro once. I found that I had NoSleep enabled (even with the app closed). If you have NoSleep installed make sure you turn it off.

When any computer is asleep it still uses power to keep the ram fresh. Another thing that macs do is to occasionally check for new emails and notifications even while asleep. This feature is called power nap. To turn that off, visit https://support.apple.com/en-us/HT204032 for information. Leslie's advice will help even more with using hibernate instead ...

I had the same problem with my MacBook Air. Tried different settings etc, didnt work. Then I noticed one pattern - If I had Chrome running, then this happens, but if I had quit chrome before closing the lid, then battery remains. So, thats what I am doing now. Making sure Chrome is not running when I close the lid.

So to calculate the holding capacity one would need the time (charging time) and the charging current. One would need a reference point from a new battery (to make it easier) how much current is flowing at what time, to allow for predicting the holding capacity. It would be a algorithm of time vs charge current.The more capacity it can store the longer the ...

It is relatively simple to replace an iPhone 5 battery. However, there are some tools which are highly recommended you buy first before continuing as you have to remove the display and can break cables in the process. Local retailers would likely be able to fix your battery for about $45-$50, if you choose to have it services either by an AASP or an ...

Apple Says: Charge your Apple lithium-ion battery whenever you want. There’s no need to let it discharge 100 per cent before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100 per cent of your battery’s capacity — but not necessarily all from one charge. For ...

Will you even be able to fit the 15" MacBook Pro's battery into the 13" MacBook? Messing with power like this only result in broken things. I highly recommend to get a new battery from Apple if it's still available. Or perhaps from a reliable third party.

Simple answer-- yes you can! there should be no any problems.

It may be worth backing up your iPod and performing a factory restore. We recently had an iPad that would discharge to flat in around 8 hours, where the rest of the set would still be going strong a couple of days later. Restarting the unit made no difference. The last thing we decided to try before returning the iPad to our supplier was a factory restore, ...
